MACHINE FOR APPLYING PAINT T0 EMBOSSED DESIGNS.

To all whom it may concern:

Be it known that 1, JOHN ENGEL, ac1t1- zen of the United States ofAmerica, residing at Green Bay, in the county of Brown and'State ofWisconsin, have invented certain new and useful Improvements in Machinesfor Applying Paint to Embossed Designs, of which the following is aspecification, reference being had therein to the ac companying drawing.

The invention relates to a machine for ap-' plying paint to embosseddesigns and is especiall used for painting the figures on license platesfor vehicles.

It is an object of the invention to provide a plurality of rollers overwhich the plate to be painted is moved so that in the passage of theplate the embossed parts of the latter receive paint from the variousrollers.

A further object of the invention embraces the provision of means formoving a plate in functional relation to the rollers so that paint isapplied in a uniform and effectual manner to the embossed portions ofthe plates.

It is also an object of the invention to provide means for scraping theoperative surface of the rollers for the purpose of evenly distributingthe paint adhering thereto.

To the accomplishment of these and related ends the invention comprisesthe means described in the following specifica tion and particularlypointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of the machine constructed in accordancewith my invention.

Fig. 2 is a longitudinal section of the Ina-- chine- Fig. 3 is a topplan view. 1

Fig. 4 is a section on the line 44 of Fig. 3, and

Fig. 5 is a detail of the driving shaft and pulley.

Referring to the several figures in the drawings, 1 designates astandard for the support of a frame 2 comprising side plates 3 and 4. Tothe side plates angular members 5 are secured which overhang with ahorizontal leg the space defined by the side plates 3 and 4 and whichterminate in ways 6 to act as guiding means for belts 7 trained aroundpulleys 8 and 9 respectively mounted at the front and rear ends of themaspeeification of Letters Patent.

chine. The sidewalls 3 and 4 of the frame 2 carry a plurality of rollerslo reierably, although not necessarily made of rubber and secured onshafts 11 which project through the side walls of the frame. Each shaft11 is extended beyond the side wall'3to carry a bevel gear 12 in meshwith the bevel gear 13 secured to a shaft 14 arranged at one'side of themachine and extending parallel to the longitudinal axis thereof. Thee'ppo site end of the shaft 11 is journaled in abracket 15adjustablysecured to the side plate 4. As indicated in Fig.- 4 aplurality of screws 13 projectingthrough slots in the bracket 15 securethe latter in adj usted position on the side wall and aset-screw 17 inthe flange 18 of the bracket 15 engages the bottom plate of the frame 2and serves as a means for shifting the bracket whereby a minuteadjustment of-the roller 10'may be effected. The shaft 14 carries at itsex tremity a bevel gear-19 in mesh with abevel gear 20 secured to thedrive shaft2l. A pulley 22 isprovided, on the shaft-21 and receivesrotative power from any convenient source. The shaft 21 is also equippedwith a pulley 23 which is encompassed by a belt 24 trained around thepulley 8.

As indicated in Fig. 2 an idler 25 at the free end of a lever 26 is heldinengagement with the belt 24 under the action of a helical spring 27which interconnects the opposite ends of the lever 26 with the frame andthereby serves as a tightener for the belt 24. The lever 26 is pivotallyinterconnected intermediate its ends to a guide member 28 which at itsupper side has grooves 29 through which the belts 7 pass. The latter aretrained around guide pulleys 36 which are arranged at convenient placeson the underside of the frame 1.

In order to prevent the excessive accumulation of paint on portions ofthe roller surfaces, means is provided to the eifect of equaldistribution of the paint therein. This means comprises plates 30 havingan end portion 31 in engagement with the roller 10 and secured to theframe 2 by a screw 32 passing through an angular plate 33 which at itsupper end is equipped with set screws whereby adjustment of the plateend 31 relative to the roller 10 may be effected.

As indicated in the figures the rollers are arranged to be partlyreceived in receptacles 34 supported on the frame 2 by legs 35.

The rece tacles 34 are filled with paint to a level su cient to insurecontact thereof with the lower portion of the rollers.

The operation of the machine is as follows:

Power being applied to the pulley 22 of the drive shaft 21 the belts 7will be rotated by the agency of the drive belt 24 interconnecting theroller 8 and the pulley 23 of the drive shaft. Simultaneously uponrotation of the drive shaft the longitudinal shaft 1a is rotated wherebythe several rollers 10 are placed in rotation. The plates having thenumbers embossed, are placed on the belts 7 such that the embossedfigures point downwardly and in the travel of these plates they aresuzcessively placed in contact with the rollers 10 of which by way ofexample three are indicated in the drawing. In the passage of the platethe latter is manually pressed down on the roller. It is obvious that bythe employment of the machine a great number of plates may be painted ina convenient and efiectual manner in a comparatively short time.

The rollers 10 are driven with the speed of the driving shaft, beingdirectly geared therewith, and the belts 7 trained around the pulleys 8,9 travel at the same rate of speed whereby the painting of the embossedpart of the plate conveyed by the belts is effe tively carried on.

While the drawings illustrate the preferred embodiment of the invention,alterations will readily suggest themselves to those versed in the art.It is therefore my intention to include all changes constitutingdepartures within the scope of the invention as indicated in theappended claims.

I claim:

1. In a machine of the haracter specified, a plurality of rollers, meansfor adjusting said rollers in vertical direction, means for supplyingsaid rollers with paint, a plurality of plates having an end portionadapted to engage said rollers for evenly distributing paint on thesurface of the rollers, means for adjusting the engagement of saidplates with said rollers, and a plurality of belts adapted to carry thework in successive contact with said rollers.

2. A machine of the character specified. a plurality of rollers, meansfor adjusting said rollers in vertical direction, means for supplyingsaid rollers With paint, a plurality of vertical plates having theirlower ends secured to a frame and their upper free ends bent to engagesaid rollers for evenly distributing the paint on the surface of therollers, a plurality of set-screws for adjusting said plates with saidrollers, and a plurality of belts adapted to carry the work insuccessive contact with said rollers.

In testimony whereof I hereunto affix my signature.

JOHN ENGEL.
